Abstract

Mechanically filtered environmental air is normally passed, by means of fans (15) which are arranged on the rotor shaft on both sides, through the cooling channels in the stator and rotor and the machine airgap (22) it order to cool a rotating electrical machine having an open cooling circuit. If the air which is taken from the environment is contaminated with hazardous materials, it is proposed to supply the prefiltered air directly to the stator and to the machine air gap and to subject only that cooling air which is to be supplied to the rotor to secondary filtering in an active-carbon filter (30). In this case, the mechanically filtered cooling air which is to be supplied to the stator and, if appropriate, to the machine air gap, is conveyed by the fans, while the cooling air which is subjected to secondary filtering and is to be supplied to the rotor is passed into the rotor on a separate path. In this case, the cooling air for the rotor is preferably conveyed by the rotor's own fan. This reduces the investment costs for the secondary filters, since only a fraction of the required quantity of air now needs to be subjected to secondary filtering. <IMAGE>
